CLOTHES-WRINGEB.

Specification of Letters Patent.

Application led J une 28, 1915. Serial No. 36,601.

To all whom it 'may conce/m.'

Be it known that I, BYRON A. WALKER, a citizen oi the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Clothes-Wringers, of which the following is a specication.

This invention relates to clothes wringers and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claim.

More particularly the invention relates to that type or wringer to which poweris usually applied and wherein some means are provided for releasing the pressure rolls in an emergency, as for example, when an operator may have been caught by the rolls. The structure exemplify/ing the invention is along the lines of that disclosed in the patent to William Robertson, issued March 9th, 1915, #1,131,087. In that structure when the pressure on the rolls is released the pressure device is thrown clear of the wringer. This is objectionable especially in view oi the fact that at the moment of release the operator would be apt to have one hand engaged or caught in the wringer.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 shows a plan view of the wringer.

Fig. 2 a side elevation, partly in section.

lFig. 3 an end elevation, partly in section.

Fig. i a'horizontal section on the line 1 -Li, the view being-from the bottom.

1 marks the upper roll, 2 the lower roll and 3 the side Stiles of the wringer. The side Stiles have the usual slots i in which the bearings 5 of the upper roll are arranged. A spring 6 exerts pressure on the bearing 5 and thus puts the rolls under pressure. A hearing cap 7 is arranged at the upper end of the spring 6. One of these bearings is arranged at each end of the wringer, each end of the wringer having a spring 6. rlhe bearing caps 7 are connected by a cross har 8. a

rlhe pressure screw 9 operates against the bearing cap. It is carried hy a sleeveshaped nut 10. The nut 10 has a lateral projection 11 on its under side. The nut eX- tends through a perforation 12 in the top bar 38', the top bar forming a permanent part of the frame. The perforation has a lateral slot. 13 permitting the`- passage of the pro- ]ection 11. A bearing plate 14 is arranged on the underside of the top bar and this is provided with the slot 15 registering with the slot 13. This mechanism is arranged at both ends of the cross bar 3a there being one of these pressure devices for each of the springs 6. The nuts 10 are put in place by passing them through the perforations 12, the projections 11 passing through the slots 13. After they have passed through the perforations the projections 11 are turned to one side of the slot. thus locking the nuts in their lower position. With the nuts in this position, the pressure screws 9 may be ad]usted for any pressure desired, this ad- Justment of pressure being the usual one. Each of the nuts 9V has an arm 16 extending from the upper end. These arms are connected by a link 17 so that both nuts may be swung together. One of the arms is provided with an extension 18 which forms a handle by means of which the nuts may be swung to release them.

The mechanism so far described is similar to that shown in the Robertson patent and operates in a similar manner. lt will be observed that when the nuts 9 are turned to release them, the springs 6 expel the mechanism with considerable violence carrying the link and attached parts with them. The object of the present invention is to obviate this diiilculty. This is accomplished by bridging the slots 13 at the top of the cross bar by means of a plate 19, the plate being secured in the cross bar by the screws 20. This allows an upward movement of the nuts, the projections 11 passing upwardly through the slots 13 to the upper end thereof. rlhis is a suihcient movement to relieve the pressure on the rolls and yet prevent the expulsion of the nuts from the frame. y

What claim as new isln a clothes wringer, the combination of a frame including a top bar with a keyhole slot therethrough; a pressure nut having a projection thereon adapted to pass through said keyhole slot and to lock on the underside Patented nay ii, reis.
